Black points: 587

Sloten Casino
Safety Index 3.3 Very low

Case summary

The player from Japan won approximately 400,000 yen while playing pachinko slots, but after successfully withdrawing 180,000 yen, the casino claimed they had violated the terms of service and confiscated the remaining balance of about 200,000 yen. The player insisted they had followed the rules and played immediately after the machine reset, yet the casino's claims of fraud continued to change, with no resolution provided despite multiple requests for clarification. The complaint was marked as unresolved due to the casino's lack of response and absence of a valid license or alternative dispute resolution service. It was noted that the unresolved status might negatively affect the casino's rating, but no further action was possible without the casino's cooperation.

Hello Houston123,

I'm Michal, and I have taken over this complaint. I have reviewed your case, and I agree that this appears to be a rather unusual situation. On one hand, as you yourself confirmed, "all bets between 22:26 and 02:47 ended in wins," which would not been possible if the machine was functioning as intended during that period.

On the other hand, I also understand your point that pachinko and certain slot games are generally played remotely through actual physical machines, which makes it quite unclear how such an issue could have been directly manipulated or exploited from the player’s side.

I will reach out to the casino to gain further insight into this issue and to explore how I might be able to assist.

I would like to invite Sloten Casino to join the conversation.



Dear Sloten Casino,

Kindly provide me with any evidence supporting the alleged violations of your terms and conditions, of which the player is being accused. You can send the information and evidence to me at michal.k@casino.guru for an independent review.

Thank you in advance.

We would like to ask the casino to reply to this complaint. We are extending the timer by 7 days. If the casino fails to respond in the set time frame, we will close the complaint as ‘unresolved’ which may negatively affect its rating.

Dear Houston123,

I have tried to contact the casino repeatedly but have had no success. I'm afraid there isn't much that can be achieved without cooperation on their side. Since the casino operates without a valid license and doesn't refer to any ADR service, there is no gaming authority to turn to.

I will mark the complaint as "unresolved" in our system. I understand this isn't a satisfactory solution to your issue. However, the decrease in the rating caused by unresolved complaints could help to change the casino's approach. If the casino decides to react, we will reopen the complaint, and you will be notified by email.

I can only recommend that you choose casinos based on their reviews and ratings in the future to avoid situations like this. I am sorry we could not be of more help on this occasion.


Best regards,

Michal
